BOOKBINDER.

To all whom it may concern.-

Be it known that 1, ROBERT J. NICHOLSON, a citizen of the United States,and a resident of the city of St. Louis, Missouri, have invented certainnew and useful Improvements in Bookbinders, of which the following is aspecification containingafull, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in bookbinders; and it consists ofthe novel features herein shown, described, and claimed.

In the drawings, Figure 1.is a perspective of a bookbinder embodying theprinciples of my invention, the book being shown in dotted lines. Fig. 2is a sectional detail through the back of the binder and taken in theline 2 2 of Fig. 3. Fig. 3 is a top plan view of the binder removed fromthe back and covers and taken looking in the direction indicated by thearrow 3 in Fig. 2. Fig. 4: is a crosssection on the line 1 .L of Fig. 2and looking in the direction indicated by the arrow, the clamp beingremoved.

Referring to the drawings in detail, the attaching-plate 5 is aflatstrip of metal adapted to reach from one end of the back 6 to the other,and the ends of the attaching-plate are turned upwardly to form the arms7 and 8, said arms being in position to engage theend faces of the bookto be bound. The attaching-plate 5 is secured between the upper section9 and the lower section 10 of the back 6. A staple is inserted throughthe arm 7 to form the prongs 11 and 12 parallel with the plate 5, saidstaple being soldered or otherwise held rigidly in place. An opening 13is formed through the arm 8, and a wedge-shaped clamp 14 is insertedoutwardly through the opening 13. A key-ring 15 is inserted through theouter end of the clamp 14.

\Vhen it is desired to apply the covers 16 and 17 to a book, the ring 15is removed. Then the clamp 1a is removed and the book is placed betweenthe arms 7 and 8, with the prongs 11 and 12 passing between the leavesSpecification of Letters Patent.

l of the book. Then thebook is opened approximately at the center andthe clamp 14 placed down in the center of the book and inserted throughthe opening 13 and the key-ring 15 inserted through the clamp.

My bookbinder is intended for telephonebooks and the like and for allkinds of books which it is desired to bind. The ring 15 may be used inhanging the book upon the wallor suitable support.

The clamp 14 is tightened up in the opening 13 by virtue of its wedgeshape and when so tightened is rigid relative to the attachingplate.

I claim 1. In combination with a pair of covers, connected by a back, ofan attaching-plate, secured to the back, arms extending upwardly fromthe ends of the attaching-plate; a staple, forming prongs, extendingfrom one arm and adapted to engage between the leaves of the book; and awedge-shaped clamp having its wider end extending inwardly to beinserted between the leaves of the book, and having its outer endprojected through an opening in the other arm.
